PUMP.

Application filed .Tune 23, 1923. Serial No. 647,339.

To all 'whom t may concer/t.'

Be it. known that I, SAMUEL S. BROWN, a citizen of the Dominion of Canada, residing at Smiley, in the Province of Saskatchewan and Dominion of Canada, have invented new and useful Improvements in Pumps, of which the following is a specification.

This invention relates to pumps for pumping oil from barrel to barrel or for pumping water or any other liquids from a source of supply to a suitable place, and has for its object the provision of a pump embodying a novel piston construction which will insure the maximum lifting power and rapidity of action, the pump structure being capable of use for a wide variety of purposes and for handling liquids of all kinds and being capable of use in con nection with wells, streams, cisterns, reservoirs or other places where the liquid is present.

The most importa-nt object is the provision of a piston construction which is so arranged that a certain amount of liquid always remains therein which will avoid any necessity for priming the pump to start the action.

An additional object is the provision of a device of this character which will be sim` ple and inexpensive to manufacture, highly eihcient in use, easy to operate, durable m service and aI general improvement in the art.

With the above and other objects and advantages in view the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which:

Figure 1 is a longitudinal section through one form of the pump showing the piston in elevation,

Figure 2 is al longitudinal section through another form showing the piston in section,

Figure 3 is an enlarged detailv view through the piston alone showing the valves in a different position to Figure 2,

Figure et is a detail cross section.

Referring more particularly to the drawings the numeral 10 designates al suitable barrel or cylinder which may have one end tapered and connected with an inlet pipe 11 as shown in Figure 1 or which may have this same end equipped with a foot piece 12 in a pump of the portable type, this foot piece being however capable of replacement by any other support which might be the platform of a well. In this second instance I have shown a flexible hose 13 entering the lower end of the barrel. In both forms the upper end of the barrel is provided with an outlet hose or pipe 14.

The piston is carried by a suitable rod 15 equipped with a handle 16 and consists of four sections designated broadly by the numerals 17, 18, 19, 2O all of which are secured together by any desired means which might be longitudinal stay bolts or which might be a species of threaded connection, as may be preferred. The section 17 has its major portion 21 cylindrical and its remaining portion tapered and formed with holes 2Q adapted to be uncovered, or covered at certain times by flaps 23 suitably hingedly mounted. The cylindrical portion 21 of this section is formed with a cylindrical bore 211 leading to branches 25 which lead out through the holes 22. The section 18 is purely cylindrical and is formed with a bore 26 registering with the bore 24. The section 19 is likewise cylindrical and formed with a bore 27 registering with the bore 26 but formed at its other end with an enlarged y chamber 28. The section 20 is likewise cylindrical and formed with a cylindrical bore 29 leading into the chamber 2S at which point I provide a valve seat 30 normally closed by a flap valve 31 suitably hingedly mounted. The lower end of the bore 29 is formed with a chamber 32 which may be oval in shape just the same as the chamber 28 and constituting the inlet. The purpose of the chamber 28 is to provide space for the valve 31 to move without interference. Between all of the sections and clamped thereby in proper position are soft leather washers 33 which of course bear against the barrel or cylinder and which are preferably cupped as shown.

In the operation it will be seen that on the down stroke of the piston all the valves 23 and 31 will open while on the upstroke they will all close. After a few strokes the suction produced in the lower end of the valve will draw the liquid thereinto and on subse quent strokes the liquid will pass through the registering bores in the piston sections and be discharged through the branches 25 and holes 22 into the upper portion of the barrel and thence out through the hose or pipe 14. In actual practice I have discovered that this piston is highly effective as it acllt) con'iplishes the pumping action with the minimum labor and diiiiculty and in a very short time. Owing to the simplicity of the construction and the eWness of the parts it will be apparent that there is practically nothing to get out of order so that the device should have a long life.

IVhile I have shown and described .the preferred embodiment of the invention it is of course to be understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claim.

I-Iaving thus described my invention I claim:

In a pump, a piston carried by a piston rod and consisting of a series of sectlons se cured together, all of said sections being formed with registering bores, cupped leather Washers secured between said sections, the uppermost section beingr formed with holes and the upper end of the bore therein being branched and leading to said holes, flap valves hinged on said uppern'iost section for covering said holes, one of thi` intermediate sections being formed with :i valve seat and a chamber-ed out portion thereabove and a flan valve hingedly mounted and co-operating with said seat'.

In testimoniv whereof I aiix mv signal ure.
